Abstract
Purely hexagonal ilmenite-type zinc metatitanate (ZnTiO3) and (Zn1âxCox)TiO3 (x = 0.5-1) ceramic powders were successfully synthesized at low temperature by a sol-gel route including the Pechini process. The process was modified by using a two-step heat treatment so as to obtain pure products, as was proved by the XRD, FT-IR and TG-DTA measurements. The thermodynamic stability of (Zn1âxCox)TiO3 products improved with increasing solubility x. The average crystalline grain sizes of the final products varied from â¼220 to 100 nm with increasing solubility x as confirmed by FE-SEM observation. The dielectric properties of (Zn1âxCox)TiO3 were measured at different frequencies and the results showed that there existed maximum values both for the dielectric constants and the loss tangents at x = 0.5.
